If you have understeer theres a couple of things you can do:

If on smooth surface lower the suspension mounts right down so they are against the chassis with no spacers (note: this changes the droop so you'll have to change that too)

Run with rear sway bar and no front sway bar.

Lay down the front shocks

Stand up the rear shocks.

Skill,
Did you lower both the front and rear suspension mounts to gain steering or only in the rear?
Could you please explain what your experience is with this tuning?

Too late...already have the HPI one.. I thought about getting the square version when they came out...

yea I did that..but the hex shaft is still to large to really get good alignment.... I may have to just machine out a larger slot...or get a thinner hex wrench.

i was at the track yesturday doing some testing with my pro4 and i noticed it had the biggest off-power push going into the corner. i add some droop to the rear and they helped a little bit, even when i run no tire-compond on my tires i still get the push on cold tires, so does anyone have any suggestions to getting ride on this problem,

I was experiencing understeer in the initial turn-in. A couple of other guys at my club were running Pro 4's and were running both front and rear suspension mounts without any spacers. This seemed to get the back end to come out a little on the turn in and made the car much more driveable.

However, I'm sure you could get even more of an effect by only lowering either the front or rear, one way will give you more grip and the other less but I'm not sure which way around it goes.

I find the setup tips in the manual very helpful to find out what things do, the first thing I would try is to run the standard rear sway bar but not the front one.
